Onsen effective for fatigue recovery and a comfortable space with a spacious desk

Only about 3 minutes by car from the Iida Interchange! A 10-minute walk from the express bus stop "Igara"! Refresh yourself after a long day at the natural Onsen "Iida Castle no Yu," known for its numerous benefits such as fatigue recovery, relief from cold sensitivity, and muscle pain. Enjoy a complimentary buffet breakfast featuring a daily-changing menu with health-conscious options like organic salads.

  • Amenities are available near the check-in counter, and you can take up to five items back to your Room. I have used many different razors, but the razor here felt gentle on my skin and was the easiest to use.Breakfast was also free, yet there was a good variety and it was delicious.There was a humidifier that helped prevent the Room from drying out. If I had one suggestion for improvement—though it may be my oversight—there was only one microwave on the first floor, so I had to wait for someone else when heating up the dinner I brought in. If possible, please add another one.

  • The Hanamomo blossoms in Hirugami came earlier than expected this year, so we decided last minute to stay on Sunday at a great price! The service was attentive and polite. The Room was compact and spotless. Amenities were well stocked, and you can even choose your pillow! Welcome drinks (coffee, alcohol, etc.) are available from 5:00 pm to 8:00 pm. The large public bath was a bit small, but there are two separate baths for men and women. The water felt silky and very relaxing. Breakfast: the mini croissants were crispy, the salad was fresh with several dressing options. The chop suey-style dish and sweet-and-sour pork had the texture of frozen vegetables, but for a free breakfast the selection was more than enough! We’d love to stay again if we have the chance—thank you very much!

About Hygiene Measures
■Measures in Response to COVID-19 Prevention■ Thank you for choosing Super Hotel. We would like to express our heartfelt gratitude to the government agencies and healthcare workers who are working tirelessly to prevent the spread of COVID-19. At Super Hotel, we prioritize the health of our guests and have strengthened our hygiene measures to ensure a safe and comfortable stay. We are also implementing hospitality practices that consider social distancing. We apologize for any inconvenience this may cause and appreciate your understanding and cooperation. 【Enhanced Hygiene Measures】 1. We will verify guest identity and conduct temperature checks at check-in. 2. Hand sanitizers are placed at the front desk and lounge entrances, and we encourage guests to use them. 3. Frequently touched areas in public spaces and guest rooms are disinfected with sanitizing solutions. (e.g., front desk counters, self-check-in machines, elevator buttons, door handles, switches, tables, remote controls, slippers, etc.) 4. Regular space disinfection is conducted in the front desk, lobby, and lounge areas. Protective screens are installed at the front desk to prevent droplet transmission. (Excludes some locations.) 5. Some Properties and newly opening Properties have introduced "photocatalytic air purifiers" that provide deodorizing and disinfecting effects. 【Front Desk and Staff】 1. Employees undergo temperature checks before work, practice thorough handwashing, use alcohol-based sanitizers, and wear masks. 2. We maintain a social distance of over 2 meters and provide heartfelt hospitality with eye smiles. 3. Thanks to our passcode system, guests can enjoy a smooth departure with no key and no need to check out at the front desk. 【Breakfast】 1. To ensure hygiene, we have changed our breakfast service to individual servings, staff-assisted portions, or providing guest-specific tongs. 【Effective Period】 From Thursday, July 23, 2020, until further notice. 2. Seating arrangements have been adjusted to maintain distance between guests. 【Large Public Bath】 1. For hygiene reasons, the use of artificial carbonated springs has been suspended at the following locations: 【Effective Period】 From Monday, April 20, 2020, until further notice. Shinagawa-Shinbanba, Shinjuku Kabukicho Please check the congestion status of the large public bath via the in-room VOD system (available at some locations). Locker usage in the large public bath has been reduced to limit the number of users. 【Three Initiatives to Boost Immunity】 We provide peace of mind to our guests through three initiatives to boost immunity. ●Point 1: Clean Air for Safety, Cleanliness, and Comfort - Diatomaceous Earth Ceilings Ceilings are made with natural diatomaceous earth, which has antibacterial and antiviral properties. It naturally regulates humidity and purifies the air, ensuring a comfortable room environment at all times. - Photocatalytic Air Purification System A clean and safe air purification system (manufactured by UVIX) with deodorizing and disinfecting effects, also used in medical facilities. - Thorough Disinfection We ensure thorough disinfection within the Property, including the placement of alcohol-based sanitizers. ●Point 2: Water Power for Immunity Boost and Stress Relief - Healthy Ion Water Healthy Ion Water, patented in eight countries, is high-energy water distributed throughout the Property, including guest rooms and baths. Its superior penetration and antioxidant properties have been proven to support health maintenance. - Natural Water + Silica Guests who opt out of cleaning during a Multiple Night Stay will receive our original mineral water, which has excellent penetration, antioxidant properties, and potential immunity-boosting effects. - Natural Onsen and High-Concentration Artificial Carbonated Springs Relax in our Natural Onsen or carbonated springs to relieve physical fatigue and daily stress. Enjoy a restful sleep while rejuvenating both body and mind. - Staff wear masks and maintain a distance of over 2 meters while providing heartfelt service. ●Point 3: Social Distancing × Hospitality for Peace of Mind - Maintaining a Distance of Over 2 Meters Staff wear masks and maintain a distance of over 2 meters while providing heartfelt service. - Eye Smiles Even through masks, we convey our hospitality with eye smiles. - No Key, No Checkout With our passcode system, there is no need to visit the front desk at checkout. We maintain physical distance while sending you off with a cheerful farewell. The above measures are explained with photos on our website. Please feel free to check them out as well.
